Auroran Convoy to Trantor

A bit of context I did for the artwork (based on Isaac Asimov's work):

Because of the economic and cultural crisis experienced by the spacer worlds during the last centuries, mainly due to the recent success of terrestrial colonies, many aurorans are forced to leave their beloved planet in search of a new home capable of sustaining them. Their homeworld, Aurora, is now a mere remnant of what it once was; greatly polluted, and undergoing severe global warming caused by a desperate last stand to boost all industrial activities in order to preserve the economy, the planet is unable to maintain the vibrant life it once had, and as shelters become more and more crowded, the equivalent to entire cities of people are being moved to the capital of the Empire: Trantor.

Still reluctant to abandon their luxurius ways, the "Elden Amadiro Convoy", constructed with the last of Aurora's riches, gives aurorans a confortable temporary home where to wait for their relocation in the recently built district of Mycogen, in Trantor. Although the voyage itself is short, a stopover on Earth is necessary, where the fastest hyperspace lanes can be taken. Provided with powerful artificial lights, large natural areas, and a decent amount of robots (which grow more and more scarce), the convoy is the last hope of Aurora to survive in the, now Earth-dominated, Milky Way. It represents all of the space worlds dreams, although most of them are already broken...
